I'm a bit puzzled that this is news. The technique of using metal or stone powder with resins to create fake metal or stones is used since years. When I was living in HK, in Sham Shui Po, I always wondered why there were these street stalls selling huge blocks of jade for cheap. Later a local friend told me it was just blocks of resin with embedded jade powder and other stuff. E.g. other stones ground up to simulate imperfections and dyes for the resin. When used with metal powders to create sculptures, jewelry, etc. the technique is called 'cold casting'. See e.g. https://www.youtube.com/watch?v=7VBVU3FNt-s https://www.youtube.com/watch?v=7VBVU3FNt-s Ofc., people do this with gold too: https://www.reddit.com/r/ResinCasting/comments/bfiixq/cold_cast_gold_dice_set_with_bonus_skull/ https://www.reddit.com/r/ResinCasting/comments/bfiixq/cold_c... The problem with all this is that these materials have plastic-like properties. The article mentions the sound the fake gold nugget make when hitting a surface sounding like plastic. This is one of the issues. The weight is another one. Surface feel/texture depends on various factors. The bottom line is: these materials look like the real thing but they don't feel/sound/behave like it.
